摘要
某些深大基坑项目由于各种原因在完工后不能及时进行后续施工,使得支护结构长期处于超期使用状态,文中介绍某工程实例通过基坑监测及时把握基坑的安全动态,切实采取锚索二次张拉以及支护桩后注浆等措施,保证了基坑超期使用的安全和稳定,可为类似工程提供参考。
Due to all kinds of reasons,some deep and large foundation pits can not be constructed on time and they are left unused with the supporting structure overtime using chronically.This paper introduces one of the experienced projects which through monitoring the foundation pit to control the dynamic of security on time,and by means of taking twice tensioning of anchor rope and post grouting of supporting piles and so on,so it ensures safety and tranquilization of overtime usage foundation pit.It can offer the reference of the similarity project.
